COACH-LATC H.

SPECIPICATEUN forming part of Letters Patent No. 314,611, dated March31, 1885 Application filed September 22', 1884. (No mode T at whom itmay concern:

Be it known that I, WM. SoHoLLHoRN, of New Haven, in the county of NewHaven and State of Connecticut, have invented a new Improvement inCoach-Latches; and I do hereby declare the following,\vhen taken inconnection with accompanying drawings and the letters of referencemarked thereon, to bea full,clear, and exact description of the same,and which said drawings constitute part of this specifica' tion, andrepresent, in- I Figure 1, a side View of said latch, the up per end ofthe lever broken off; Fig. 2, ahorizontal section through thelever-pivot.

This invention relates to an improvement in that class of coach-latcheswhich are set into a mortise in the edge of the coach-door, with a leverextending from the latch up through the window-sill in the door, and bywhich lever the occupant may draw the bolt from the inside of thecarriage. In the best construction of theselatches the bolt is simply astraight longitudinal bar extending through the faceplate of the caseand supported upon the inside of the case, combined with a lever havinga hook-like engagement with the bolt, a spring applied to the bolt toforce it home, and which spring is relied upon to support the lever, andthis spring, if the bolt is permitted to throw outward to its fullextent into the keeper, will hold the lever so as to prevent itsrattling, but if the bolt meet with an obstruction to prevent itsentering the keeper, as by friction upon the keeper, or otherwise, thenthe lever is left free and produces a disagreeable rattling as thecarriage runs. Again, in the usual construction, the lever is hung upona pivot in the case, the pivot being a screw introduced through the endof the lever, tapped into the case, the lever working on the barrel orbody of the screw. While such a construction serves a very good purposeas a pivot, unless the fitting of the lever upon the screw be perfectthe movement of the lever frequently loosens the screw, and gives to thelever a freedom which will produce the beforementioned disagreeablerattling.

The object of my invention is to overcome these difliculties; and theinvention consists turn.

in the construction as hereinafter described, and particularly recitedin the claims.

A represents the main plate of the case; B, i

the faceplate, C, the bolt extending through the faceplate andsupportedin a bearing, D, upon the under side of the case. The inner endof the bolt is turned up into hook shape, to form the arm E, againstwhich the lever may work.

F is the lever which extends down through the top of the case to nearits lower edge, where it is secured upon a pivot, a. This pivot is castor made as an integral part of the case, as seen in Fig. 2. The lowerend of the lever is fitted thereon as a bearing, and so as to turnfreely. The end of the pivot is tapped, and into it a screw, 1), isintroduced, the head of which takes its bearing hard upon the pivot, butextends over slightly onto the face of the lever, so as to prevent. thelever from slipping off the pivot. vUnder this construction of the pivotthe lever cannot loosen the screw, but if from any cause the screwshould be loosened, the pivot remains as a iirm and substantial bearingupon which the lever may The lever extends to the rear of the bolt,thence curved forward and downward to form an arm, (I, to engage the armE of the bolt, and so that by pulling the lever inward the bolt will bedrawn, as indicated in broken lines.

G is the boltspring. It is made from wire, one end introduced into aslot in a stud, 0, formed as an integral part of the plate A. The otherend of the spring extends upward to engage the bolt, the tendency of thespring being to throw the bolt forward or outward.

To prevent the rattling of the lever and give it a support independentof the bolt, I apply a spring, H, upon the back of thelever. This springis made from a piece of wire, one end introduced into a slot in a stud,f, which is formed as an integral part of the case, the other bentaround to take its bearing on the back of the lever, as shown. By thisconstruction and arrangement of the springs one end is firmly andimmovably fixed in the case, and if perchance the springs break they areeasily repaired without resort to a locksmith, as it is only necessaryto remove the broken spring and introduce a piece of wire bent intoshape. This construction and arrangement of springs overcomes a seriousdifficulty heretofore experienced in this class of locks, from the factthat the construction and attachment of the springs in the previousconstructions are such as to require considerable mechanical skill torepair or apply them. The pivot of the lever is directly under itsbearing upon the bolt, the spring bears upon the lever to force it intoits extreme forward position, and there hold it independent of the bolt,and so that whether or not the bolt be completely thrown, the lever willbe firmly held, and the rattle of the lever is impossible.

It will be understood the bolt is operated from the outside by the usualknob-like attachment working through the huh I in the usual manner, thesaid hub being in the usual connection with the bolt, but not shown.

I claim- 1. In a coach-latch, the combination of the case, the pivot a,constructed as an integral part of said case and internallyscrew-threaded, the latch-boltO, the lever F, hung upon said pivot andconstructed to engage with the said bolt, and the headed screw b,introduced in the end of said pivot, the head of the screw taking abearing upon the end of the pivot, of greater diameter than the pivot,and so as to extend over the pivot onto the surface of the lever, with aspring adapted to force the said bolt outward, substantially asdescribed.

2. In a carriage-latch, the combination of the case, the bolt 0,extending through the faceplate, its inner end supported in a bearing,D, and terminating in an arm,E, the lever F,extending through the upperedge of the case downward and hung upon a pivot, at, below said lever,also constructed with an arm, d, to engage the arm E of the bolt, thespring H, having one end secured in the slot of a fixed stud, f, formedas an integral part of the case, said spring arranged to bear upon thelever in dependent of the bolt, and aspring, G, arranged to act directlyupon the bolt, substantially as described.

3. In a carriage-latch, the combination of the case, the bolt 0,arranged through the faceplate of the case, its inner end supported in abearing, D, and terminating in an arm, E, the lever F, extending throughthe upper edge of the case downward, hung upon a pivot, a, formed as anintegral part of the case, said lever constructed with an arm, d, toengage the arm Eof the bolt, the spring G,made from wire, one endarranged in a slot in a stud, 6, made as an integral part of the case,the other engaged with the bolt, and a spring, H, ar-

ranged to bear upon the lever independent of the bolt, substantially asdescribed.
